Kelpak is a kelp concentrate which is manufactured using a unique cell-burst process without heat, chemical digestion or dehydration. This patented process ensures maximum retention of the auxins and cytokinins found in this species of kelp. Kelpak also contains a wide range of nutrients, vitamins and amino acids.

The combination of plant growth regulating hormones impact upon plants in different ways according to the plant growth stage and condition. Auxins and phlorotannins improve root growth; polyamines help to reduce the impact and symptoms of abiotic stress and brassinosteroids promote pollen tube elongation resulting in better fruit set.
